I'm in the "it's a different app" camp as well, and whether it is viewed as worse or better is very dependent on how you use it. I would not say it depends on whether you are a new or occasional user vs professional. That belittles a lot of us long-time and new professional users who find it works fine for us, and we like many of the changes over Legacy. That is not denying there are bugs, old and newly introduced that need attention, but for the most part, personally, I get along fine, though improvement is always welcome.
I think the difference is that those with highly customized workflows built on Legacy and, or who want the utmost speed will be disappointed with the current state of V10. Some will get used to the differences in V10, and others never will. Evernote should continue improving speed, reducing user friction, and adding some customization that many found useful in Legacy. Those who can't get past the differences can either work constructively here to help improve the app or maybe consider moving to one that works better for their use case.
This wasn't directed at any particular post. These are just some general comments that I had.
